The first flight was given as 120 feet in 12 seconds. Doing the math

[tex]\dfrac{\dfrac{120}{5280} }{\dfrac{12}{3600} }[/tex]

gives 6.82 miles / hour

But the history of what made this flight possible was an engineering act of very careful experimentation and a great deal of thought on how to use mathematics to solve flight problems. It's worth looking up.
